BUNG -SEAT CONSTRUCTION.

Application filed September 16, 1925. Serial No. 56,682.

This invention relates to improvements in bung-seats and moreparticularly to constructions adapted for use in connection with steelbarrels and other types of metal con- 6 tainers.

It is one of the objects of the invention to provide a form ofconstruction embodying parts which are adapted for manufactureindependently of the containers and which may be sold to containermanufacturers and readily a plied to the containers by a simple formpress. A further object of the invention is to provide a bungseatstructure that will be attached to the container in a substantial mannerso as to be capable of withstanding the blows to which the bung issubjected in handling the containers and in connection with efforts toloosen the bung when it is to be removed. A further object of theinvention is to provide a bung-seat structure that will be so attachedto the container as to form a tight joint therewith which will not beliable to become loosened and leaky and which is also adapted 25 to bewelded or soldered if ever necessary.

Other objects of the invention and features of novelty will be apparentfrom the following description taken in connection with the accompanyingdrawings, of which:

Fig. 1 is a plan view of a structure embodylng my invention;

Fig. 2 is a transverse section thereof on the line 22 of Fig. 1;

Fig. 3 is a, transverse section through the and,

Fig. 4 is a transverse section through the assembled parts and the diesby which they are secured together in the manner illustrated in Fig. 2.

Referringto the drawings, 10 indicates a section of the barrel orcontainer wall in which there is formed an inward depression 11 havingan opening 12 therein which is surrounded by a relatively shortoutwardly projecting flange 13. The bung-seat, proper, comprises the twotubular members 14 and 15, the member 14 having a laterally projectingflange 16 that is adapted to be arranged on the interior of thecontainer wall. The outer end of the member 14 is flared slight- 1 asshown at 17, for apurpose to be later described. The member 15 isinternally threaded to receive the bung and is proparts of the structureprior to assembling,

vided with a laterally projecting hook-like flange 18. The members 14:and 15, prior to assembling and after manufacture, are of the form shownin Fig. 3' and these mem bers are assembled in the opening 12, as

shown in Fig. 4.

The parts are secured together by means of a pair of dies, the die 19being arranged,

the flange 13 being also turned laterally to some extent, to interlockwith the edge of the flange 18, as shown at 22. The die 19 carries aplurality of small projections 23, preferably four, which initiallyengage the inner side of the flange 16 and, when the parts are forcedtogether, these projections form small indentations or depressions 24 inthe flange 16, and in the wall of the container, which serve to securethe parts against turning in the container wall.

From the foregoing it will be apparent that I have provided acomparatively simple structure and that the parts 14 and 15 are the onlyparts that are subjected to material deformation, so that these partsmay be made of. the proper quality of steel to withstand the deformationwhile the wall of the container, which is not substantially deformed inthe operation, maybe made of the relatively lower grade steel from whichit is usually desirable to manufacture containers, in order to reducethe cost to a minimum.

The parts of the bung-seat structure are so interlocked that the wall ofthe container is securely clamped between the flanges of the members 14and 15 and a tight joint is provided. a On account of the relativelylarge size of the flanges that are provided on the inside and outside ofthe container wall, the seat structure is so substantially secured tothe wall that it is not liable to be loosened by the blows to whichstructures of this kind are subjected in service. ,The structure has thefurther advantage that the flange 18 may be conveniently welded orsoldered to cent end of the first-mentioned member to tainers and thelike comprising a pair of tubular members adapted to be telescopicallyarranged in an opening in the wall of the container, said members havinglaterally projecting flanges adapted to be arranged on one side of thewall and pressed into interlocking engagementand one of said membershaving laterally projecting flanges adapted to be positioned on oppositesides of said wall and to cooperate with the first-mentioned flanges toclamp said wall therebetween and thereby form a tight joint with thewalk v 3. As a new article of manufacture, a bung-seat structurecomprising a pair of tubular members adapted to be telescopicallyarranged, one of said members having a hook-like laterally projectingflange which, coo crates with the end of the other member to orm alaterally projecting flange thereon and interlock therewith when saidmembers are forced together. e

4. As a new article of manufacture, a bung-seat comprising a pair oftubular members adapted to be telescopically arranged, one of saidmembers having a laterally projecting flange adapted to be arranged onone side of a container wall and the other member having a hook-likeflange ada ted to be arrangedon the opposite side 0 the container walland to cooperate with the adja form a flange thereon with which thehooklike flange interlocks when said members are forced together toclamp the container wall therebetween.

5. In bung-seat structures, the combination of a wall having adepression therein with an opening which is surrounded'by a relativelyshort flange projecting int'os'aid' depression, a tubular memberarranged in said opening and having two laterally projecting flanges oneof which engages said wall on the side opposite said depression,

' and a tubular member arran ed within said first-mentioned tubular memer and having a hook-like flange interlocked with the other of saidflanges on said first-mentioned member.

6. In bung-seat construction, the combination of a wall having anopening which is surrounded by a flange, a tubular member havingtwolaterally projecting flanges arran ed,respectively, on opposite sidesof said wal and a tubular member, arranged within the first-mentionedtubular member and hav ing a hook-like flange which is interlocked withone of the flanges on said first-mentioned memberandcooperates with theother flange on the latter memberto clamp said wall therebetween.

7. In bung-seat construction, the combination of awall having an openingwhich is surrounded by a flange, av tubular member havingtwo laterallyprojecting flanges arranged, respectively, on opposite sides of saidwall, and a tubular member, arran ed within the first-mentioned tubularmem er and havin a hook-like flange which is interlocked wit one of theflanges on'said firs";- mentioned member and cooperates with the otherflange on the latter member to clamp 'said wall therebetween, and saidwall and one of said flanges havin coo rating deressions to hold saidmem rs rom turning in said opening. In testimony whereof, I hereuntoaflix my signature.
